Okay, we know the DVDs are good. If you put the 20 into target disk mode can you reformat the HD from the 17? Go to partion in Disk Utility and choose 1 partition, in Options choose GUID, HFS+ journaled.

After that you can insert one of the DVDs into the 17, boot from it, and choose the target disk moded 20 as the install HD.

Yes, tried Apple + s and Apple + v & Shift. No luck. I have trawled the Internet and tried everything suggested. Apple were no help. Something tells me there is a PRAM Reset button on the motherboard. Ever heard of it?
